I unable to unlock the bootloader for HTC 816G. I am trying to do this on a windows 10 laptop. The issue is that when I enter command 'adb devices', there is no device found when the phone is on fastboot mode. However, the same command works when the phone is on normal boot mode. I have installed HTC Sync and there seems to be no issue with driver. However, I tried to manually update the driver to "Android adb device" but issue persisted. I can see the phone serial number when I run 'fastboot devices' when phone is on fastboot mode. I tried to do this on an Ubuntu machine and still the same. Please assist.
Do let me know if you require any more details.
